I think I'd consider it a bug: I've disabled stonith, so dlm shouldn't wait forever for a fence operation that isn't going to happen.
I reckon if you set the args parameter of your ocf:pacemaker:controld resource to "-f 0 -q 0", you'll have DLM ignoring fencing.
Yes, that does the trick. Thank you (for helping me make my cluster as unsafe as I want it to be :)

In my mind, with two nodes, a cloud passes over the moon for a second, it goes momentarily dark, and when the light comes back both nodes are found dead of gunshot wounds, even though they're both holding hands over the shared storage fire with SBD. But that's a separate problem.
If DLM is ignoring fencing, everything that uses DLM is also going to ignore fencing, so if you've got (say) an OCFS2 filesystem on top of your CLVM volume, your filesystem will potentially be toast in a split-brain situation.
Yes, and I guess it would also cause problems if we used CLVM with exclusive locks.
Thanks again.
